2 Claims.

This invention relates to the construction of towers, masts, scafiolds and analogous structures.

The principal object of the invention is the provision of means whereby structural components may be quickly, easily and rigidly connected with each other to form a structure of the types mentioned.

A further object is the provision of an improved construction for integrating structural elements to form a tower and the like which is effectually braced so that the finished structure will be rugged, durable and stable.

With the foregoing, other objects of the invention will appear when the following specification is read in conjunction with the accompanying drawing, in which--- i Fig. 1 is a fragmentary side elevational view of a structur embodying the features of the invention.

Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1.

Fig 3 is a fragmentary side elevational view on an enlarged scale to more clearly bring out the main features of the invention.

Fig. 4 is a collective view of the certain parts which are shown assembled in Fig. 3.

In the present instance there is shown by way of example a structure in the form of a quadrilateral pyramidal tower which may be of any suitable dimensions as to height and width. The tower is constructed of sections, including legs l and bracing members or tie bars II and I2, connected with the legs NJ in accordance with the present invention.

The legs l0 constitute the main supports for sustainin the weight and the strains and stresses from any causes. Each leg l0 consists of a plurality of members l3 of suitable length and different cross-sectional sizes so as to be telescoped. Each member I3 consists of a metal tube, round in cross-section. As shown, the legs Ill are arranged slantwise to provide a pyramidal structure but the legs may be disposed upright in a vertical position.

In accordance with the invention, a joint is provided between adjacent ends of the members of each leg H], for this purpose; each leg member l3 has fixedly secured thereto a collar [4 to provide an extension beyond the collar spaced a suitable distance from its lower extremity. In the present instance the collar I4 is welded to the member 83, as at 15. Wings or gussets l6 are rigidly secured to the collar M, as by welding. Obviously, the collar l4 may be omitted and the gussets may be secured directly to the member [3. The wings or gussets are arranged at a right angle with respect to each other and project laterally. Wings or gussets I8 are rigidly secured to the member l3 at the upper end, as by welding l 9. The wings or gussets 18 are arranged at a, right angle with respect to each other and project laterally in the same manner as the wings or gussets I6, so that these parts will be disposed in pairs with the wings or gussets of each pair disposed edgewise in the same plane while the lower end portion of one member I3 is telescoped into the upper end portion of another member l3. Each collar I 4 limits the extent of the insertion of one leg member l3 into another, because the collar M on one le member abuts the end of a contiguous leg member. An oblong plate 20 is rigidly secured flatwise to the gussets l6 and [8 of each pair overlapping the same in any suitable manner, as by the use of fasteners 2|, received in holes 22 and 23 in the gussets and plate, respectively. In this manner an upper and lower leg member [3 are rigidly connected in telescoping relation to form the legs II).

The legs l0 thus fabricated are rigidly connected in the desired spaced relationship by the/brace members H and I2. There is a brace member H arranged horizontally between each pair of plates 20 at each side of the tower, and the opposite ends of said brace member I l are rigidly secured to said plates 20, respectively, as by welding 24. A brace member 12 is arranged diagonally between a gusset I6 on the lower end of a leg member [3 and a gusset [8 on the upper end of a second leg member H3 at each side of the tower, and the opposite ends of said brace member l2 are rigidly secured to said gussets I6 and I8 by some of the fasteners 2|.

From the foregoing it will be understood the various parts are integrated in such manner as to produce a structure which will be strong, durable and stable.

I claim:

1. A tower including spaced legs, each leg comprising joined tubular members, each joint between the leg members comprising an extension and shoulder on one leg member respectively 'telescoped into and abutting the end of a socket formation on an adjacent leg member, a gusset plate secured adjacent the end of each leg member and a connecting plate extending across the joint 1ine between the leg members and secured to a pair of adjacent gusset plates, a horizontally positioned brace member directly secured to each pair of connecting plates on two opposed legs, and diagonally positioned brace members each directly secured to a pair of gusset plates of two opposed legs.

J2; In a tower, spaced legs each composed of tuhular members joined in pairs in telescoping relation, each joint between the le members including a gusset plate secured adjacent the end of each leg member and a connecting plate extending across the joint line between the leg members and of two opposed legs.

4 secured to a. pair of adjacent gusset plates, a horizontally positioned brace member directly secured to each pair of connecting plates on two opposed legs, and diagonally positioned brace members each directly secured to a pair of gusset plates HAROLD COHEN.
